Design-proportion maths as an API, computed locally and deterministically. The divide endpoint splits a length by the golden section, the division beloved of artists and designers in which the whole is to the longer part as the longer is to the shorter, both ratios equal to φ = (1+√5)/2 ≈ 1.618 — so 100 splits into a 61.8 longer segment and a 38.2 shorter one — and can also extend a single segment to its larger or smaller golden partner. The rectangle endpoint gives the other side and the area of a golden rectangle from either side, the shape that leaves a smaller golden rectangle when you remove a square. The scale endpoint builds a modular (typographic) scale — base · ratio^step across a range of steps up and down — for harmonious type sizes and spacing, taking a numeric ratio or a named musical one such as minor-third (1.2), major-third (1.25), perfect-fourth (1.333) or golden (φ); a 16-base major-third scale gives 16, 20, 25, 31.25 and so on. Lengths are unit-agnostic. Everything is computed locally and deterministically, so it is instant and private. Ideal for graphic-design, web-design, UI, typography, layout and architecture app developers, type-scale and proportion tools, and design systems. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is proportion and scale; for pixel-density and print sizing use a PPI/DPI API.

CIE colour science as an API: convert colours through the device-independent spaces and measure how different two colours really look. The convert endpoint takes a colour as hex, RGB or CIELAB and returns it in sRGB hex, RGB, CIE XYZ and CIELAB (D65 white point). The distance endpoint computes the perceptual difference between two colours with all three standard Delta-E formulas — CIE76 (plain Lab distance), CIE94, and CIEDE2000, the modern and most accurate metric — and tells you whether the difference is perceptible. The nearest endpoint finds the closest named colour to any colour by CIEDE2000. This is the maths behind colour matching, print and brand-colour QC, and tolerancing — distinct from simple hex/RGB/HSL conversion. Everything is computed locally and deterministically, so it is instant and private. Ideal for print and prepress, brand-colour compliance, textile and paint matching, image processing and computer vision, and design tooling. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 4 endpoints. This is CIE colour difference; for hex/RGB/HSL/CMYK conversion, palettes and WCAG contrast use a colour API.

Resolution, print-size and pixel-density maths for print, design, photography and screens. The resolve endpoint takes any two of pixels, DPI and physical length and computes the third, returning the size in inches, centimetres, millimetres and points — so you can answer "how big will a 3000-pixel image print at 300 DPI" or "what DPI do I get printing 3000 px at 10 inches". The ppi endpoint computes a screen's pixel density from its resolution and diagonal size, plus the dot pitch in millimetres, the total megapixels and the aspect ratio. The convert endpoint converts a length between pixels, inches, centimetres, millimetres and points (PostScript points, 1/72 inch), using a DPI when pixels are involved. Everything is computed locally and deterministically, so it is instant and private. Ideal for print and prepress, graphic and web design, photography, and screen and display specs. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 4 endpoints. This is DPI and print-size maths; for aspect ratios and resizing use an aspect-ratio API and for general unit conversion use a unit API.

Name any colour. The nearest endpoint takes a colour as a hex, an rgb() value, an r,g,b triple or another name and returns the closest of the 140+ CSS named colours — matched perceptually with CIE76 Lab distance, not naive RGB, so the name actually looks right — along with the distance and whether it is an exact match. The name endpoint resolves a CSS colour keyword (e.g. rebeccapurple, cornflowerblue) to its hex and RGB, and list returns the whole named-colour set. Perfect for design tools and pickers, accessibility and theming, turning brand hex codes into human labels, and naming colours in generated palettes. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 4 endpoints. Distinct from colour conversion / palette / contrast tooling, which does not name colours.

Generate colour gradients and colour scales programmatically. Produce an evenly-spaced scale of N colours between two or more stops (interpolated in a perceptually smooth colour space — lab, lch, oklab, oklch — or plain rgb/hsl), get a single interpolated colour at any position between two colours, and build a ready-to-paste CSS gradient string (linear with any angle, or radial) from a list of stops. Colours accept hex (#f00, #ff0000) or CSS names (red, steelblue). Perfect for data-visualisation colour ramps, heatmaps, chart palettes, theme generation and UI backgrounds. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 4 endpoints. Distinct from colour conversion / harmonious palettes (one base colour) and image palette extraction.

See your colours the way colour-blind users do. Pass a hex colour (or a whole palette) and get back how it appears under each major colour-vision deficiency — protanopia (red-blind), deuteranopia (green-blind), tritanopia (blue-blind) and achromatopsia (total colour blindness) — as simulated hex and RGB values. Roughly 1 in 12 men and 1 in 200 women have some colour-vision deficiency, so this is ideal for accessibility testing of UI themes, charts, maps, status colours and branding: simulate your palette, spot colours that become indistinguishable, and fix them before you ship. Pure local matrix transforms — no key, no third-party service, instant. Live. 4 endpoints. Distinct from colour conversion and contrast tools.

Suporta PNG, JPEG, BMP, TIFF e GIF. Ao vivo. 2 endpoints. Construído para ferramentas de temas e design, geração automática de cores de UI a partir de obras de arte ou fotos de produtos, extração de cores de marca e marcação de imagens. Distinto de um conversor de cor única ou serviço de redimensionamento/informação de imagem. Sem chave upstream.

The open-source icon universe — Iconify — as an API. Search across 200,000+ icons from 200+ icon sets (Material Symbols, Material Design Icons, Font Awesome, Tabler, Lucide, Phosphor, Simple Icons, brand logos and more); get any icon's SVG path, dimensions and a ready-to-use, copy-paste `<svg>` string plus a direct .svg URL; and browse the icon sets with their author, license and icon count. Every icon is addressed by a simple `prefix:name` id (e.g. mdi:home, logos:github). Live from the official api.iconify.design. Ideal for design tools and icon pickers, no-code and website builders, documentation and component libraries, and any app that needs scalable icons. Open-source icons, each with its set's license.
